Solution Overview

Problem

Conventional processing machines are limited in processing workpieces with smaller dimensions due to the inability to effectively pick up and convey small workpieces from their processing position.

Innovation Solution

A manipulation device is designed to feed workpieces from their processing position to the conveying device, featuring a gripper area that can reach under a traverse, equipped with a workpiece manipulation element such as a suction cup, allowing for temporary mechanical connection and movement of small workpieces to the conveyor device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the conveyor device is arranged to convey workpieces under the traverse, then the processing unit can reach any point on the workpiece, but small workpieces cannot be picked up by the conveyor device from their processing position

Engineering Contradiction:
Improveprocessing unit reachabilityVSAvoidworkpiece pickup capability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

A manipulation device is introduced as an intermediary between the processing unit and the conveying device. This manipulation device includes a manipulation element that can assume a workpiece-manipulating position beneath the traverse to pick up small workpieces from the processing position, then transfer them to the conveying device. The manipulation device acts as a mediator that enables workpiece handling in the narrow space under the traverse where the conveying device cannot directly access the processing position.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Extent of automation

If the manipulation device is accommodated on the same side of the traverse as the processing unit, then both can be moved along the traverse, but they interfere with each other's operation

Engineering Contradiction:
Improveautomated movement along traverseVSAvoidspatial interference
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The manipulation device is positioned on the opposite side of the traverse relative to the processing unit, utilizing the vertical dimension and lateral space beneath the traverse. This spatial arrangement in another dimension allows both the processing unit and manipulation device to operate simultaneously without interference, while both remain movable along the traverse direction.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
